To all whom it may concern:

Be it known that I, CHARLES L. MEYER,

a citizen of the United States, residing at Omaha, in the county of Douglas and State of Nebraska, have invented certaln new and useful Improvements in Fastenlng Devices for Plaster-Board and the like, of which the following is a specification. V

This invention relates to the general art of building structures, and has reference more particularly to a new and improved device in the nature of a supporting clip ill for securing blocks or plates of plasterboard and like material in place in the formation of ceiling and wall constructions wherein such plaster board is used in lieu of wooden or metallic lathing as a foundation for a finish surface of plaster.

The object of the invention is to provide a simple, cheap, and easily manipulated fastening device which, in its application to its intended use, may be temporarily secured to an element of the centering or false work of a concrete floor or wall structure, and be permanently anchored in the latter by the fragment of the concrete floor and floor beam and-the false work or centering forming the same, andshowing my improved fastening device temporarily mounted in an element of the false work and permanently anchored in the concrete of the floor beam. Fig. 2 is a perspective elevationof the fastening device in the form in which it is manufactured for application to its intended use. Fig. 3 is a view similar to Fig. 1, but showing the false work removed, and the lower portion of the fastening device, bent downwardly to plaster-board-receiving position. Fig. 4c is a view similar to Figs. 1 anti 3, but showing the plaster-board in place and the holding device operatively engaged with the latter, and Fig. 5 is a bottom plan view of Fig. 4.

Referring to .the drawing, 6 designates a concrete floor and 7 one of the integral concrete girders or beams supporting the same, the floor; and beam structure being molded on centering or false work comprising the ordinary mold members 8 and 9, this latter belng a wooden plank on which the edges of the members 8 are supported and which, in cooperation with the side walls of the members 8, forms the mold for the girder or beam 7.

Fig. 2 shows a perspective view of my improved fastener or clip in the preferred form in which it is manufactured for application to thegirder or beam 7 during the molding of the latter. This holder or clip is preferably cut and stamped by dies from an integral strip of sheet metal and comprises a vertical stem or shank member 10, a. depending pointed tongue 11 at the lower end of the shank member 10, a pair of fingers 12 extending laterally ofand at right angles to the lower end of the shank member 10, and a laterally and downwardly pro ect1ng spur 13 punched and pressed from the shank member 10.

In the practical application of this de- I vice, the false work for the floor and beams having been erected, a series of these devices are temporarily mounted at spaced intervals on the plank 9 that form the base of the beam mold, being secured thereto by driving the tongue llinto the upper surface of.,,the plank 9 until the fingers 12 rest upon said upper surface and the shank 10 projects vertically thereabove, all as clearly shown in Fig. 1. The concrete is then poured and allowed to set, after which the false Work is removed, and the fingers 12 are readily bent down into. a substantially vertical position in the plane of the shank member 10, all as clearly shown in Fig. 2. The plaster-board blocks, identified by the reference numeral 14, are then placed beneath the girder or beam 7 with their proximate edges lying against the opposite sides of the depending fingers 12, and then, by hammer or other suitable tool, the fingers are bent back in opposite directions to securely cla-mp the edge portions of the plaster-board blocks to the underside of the beam-7 in the manner clearly indicated in Fig. 5.

The described device has several advantages over devices for the same general purpose heretofore employed. It is a single or one-piece structure, it is directly anchored in the concrete of the beam without the aid of any separate fastening device, it can be I board at present known, some of which use easily and cheaply made from sheet metal with a negligible amount of waste, and it affords a very strong and secure anchorage or fastening for the plaster-board.

The term plaster-board as used herein is intended to include the various types of such the-like, comprising a shank member adapted to be embedded in a concrete supporting structure, a tongue narrower than and depending from the lower end -of the shank gmember and adapted tobe driven into an element of. the mold or false work of suchconcrete structure whereby said fastening device is properly positioned, and a laterally extending finger on the lower end of the shankmember adapted to be bent downwardly and thence over the'edge portion of a plaster-board or similar block to secure the latter to said concrete structure.

.2 As a new article-of manufacture, a onepiece sheet metal fastening device for plaster-board blocks and the like, comprising a shank member adapted to be embedded in a concrete supporting structure and formed with a laterally projecting spur to anchor the same in place, a tongue on the lower end of said shank member adapted to be driven into an element of the mold or'false work of such concrete structure whereby to position said fastening device in place, and a laterally extending'finger adapted to be bent downwardly and thence over the ed e portion of a plaster boarder similar b ock to secure the latter to said concrete structure.

3. As a new article. of manufacture, a onepiece sheet metal fastening device for plastor-board blocks and the like, comprising a shank member adapted to be embedded in a concrete supporting. structure and formed with a laterally pro ecting spur to anchor the same in place, a central tongue on the lower end of said shank member adapted to -be driven into an element of themold or false work of such concrete structure .whereby to position said fasteningdevice in place, and a pair of laterally extending fingers on either side of said tongue, respectively, adapted to be bent downwardly and thence over the proximate edge portions of a pair of plaster-boards or similar blocks to secure the latter to said concrete structure.
